> Doing it with an LLM makes it just completely useless

There can be other valid perspectives than your own.

Different people code for different reasons.

Some see it as a means to an end... "I want X as an end result and I don't care how I get it."

Others see it as an art form and something special to them; their sense of worth is tied to their knowledge and experience in something that not just anyone can do (without an AI).

OP uses an LLM because they just want the end result. You might write code for different reasons entirely. Neither is "wrong" or "useless."
